How to split a string into chunks of two characters each in Rust

Answer 1

fn split_string_into_chunks(s: &str, chunk_size: usize) -> Vec<String> {
    let mut chunks = Vec::new();
    let length = s.len();

    for i in (0..length).step_by(chunk_size) {
        // Extract the substring and push it to the chunks vector
        let end = usize::min(i + chunk_size, length);
        chunks.push(s[i..end].to_string());
    }

    chunks
}

fn main() {
    let s = "abcdefghijk";
    let chunk_size = 2;

    let chunks = split_string_into_chunks(s, chunk_size);

    println!("Chunks of two characters:");
    for chunk in chunks {
        println!("{}", chunk);
    }
}
